How to Start a Small Business in 2026: 12-Step Guide
How to start a small business in 2026: 12 steps from idea and plan to LLC, EIN, licenses, bank account, taxes and your first invoice, with a cost example.
Quick answer: To start a small business, validate your idea with real customers, write a simple business plan, estimate startup costs, choose a legal structure (sole proprietorship or LLC), register your name, get an EIN, obtain licenses and permits, open a business bank account, set up bookkeeping and invoicing, sort out taxes and insurance, then launch and market to your first customers.
This guide walks through how to start a small business in the United States in 12 practical steps, in the order most owners should do them. Each step links to a deeper guide, and at the end you will find guides for starting specific businesses, from cleaning and consulting to food trucks and trucking. It is general information, not legal or tax advice; rules vary by state and city.
What does it mean to start a small business?
Starting a small business means creating an organization that sells goods or services for profit, with the legal registrations, tax accounts and financial systems it needs to operate. The US Small Business Administration (SBA) generally treats most businesses with fewer than several hundred employees as small, but most new businesses start with one owner and no staff. The SBA's 10 steps to start your business is a useful official checklist; the steps below follow a similar order with more practical detail on money and billing.
Step 1: Choose and validate your business idea
The best small business ideas sit where three things overlap: a skill you have, a problem people will pay to solve, and a market you can reach. Before spending money, test demand:
- Talk to 10 to 20 potential customers about the problem and what they pay today.
- Check competitors' prices, reviews and how far ahead they are booked.
- Pre-sell: take a deposit, a pre-order or a signed quote before buying inventory or equipment.
- Run a small paid test, such as a local ad or marketplace listing, and count inquiries.
Service businesses are usually the cheapest to test. If you are deciding between options, our guides on starting a cleaning business, starting a consulting business and starting an online store show the costs and steps for three very different models.
Step 2: Write a simple business plan
A business plan forces you to answer the hard questions on paper: who buys, at what price, how they find you and when the business breaks even. A one-page plan is enough for most solo businesses; lenders want a fuller version. Use our free business plan template, which includes a one-page version and a worked financial example. Build your revenue line with a month-by-month sales forecast rather than a single annual guess.
Step 3: How much does it cost to start a small business?
List every cost before your first sale, then add a reserve to cover fixed costs while sales ramp up. The figures below are illustrative for a home-based service business; see our full guide to startup costs for a worksheet and the IRS $5,000 startup cost deduction.
| Item | Illustrative cost |
|---|---|
| LLC filing fee (varies by state) | $50 to $500 |
| Local business license | $50 to $400 |
| EIN from the IRS | $0 |
| Laptop, phone and basic equipment | $0 to $2,000 (if not already owned) |
| Website and domain (first year) | $100 to $600 |
| General liability insurance (first year) | $300 to $1,200 |
| Accounting software | $0 to $400 a year |
| Launch marketing | $200 to $1,500 |
| Reserve: 3 months of fixed costs | $600 to $3,000 |
Fund the launch with savings where possible. If you need more, compare SBA loans, equipment financing and a business line of credit.
Step 4: Choose a business structure
| Structure | Liability protection | Default federal tax | Paperwork |
|---|---|---|---|
| Sole proprietorship | None; owner personally liable | Schedule C on personal return | Minimal |
| Single-member LLC | Yes, if run properly | Same as sole proprietor unless S corp elected | State filing, annual report |
| Partnership / multi-member LLC | LLC: yes; general partnership: no | Form 1065, K-1s to owners | Operating or partnership agreement |
| S corporation (tax election) | Yes | Pass-through; owner must take reasonable salary | Payroll, Form 1120-S |
| C corporation | Yes | 21% corporate tax, then tax on dividends | Most formal |
For most first-time owners the choice is between a sole proprietorship and an LLC. Our comparison of LLC vs sole proprietorship and the overview of business entity types explain the trade-offs. If you choose an LLC, follow how to start an LLC, appoint a registered agent and sign an LLC operating agreement, even as a single member.
Step 5: Register your business name
Check that your name is available with your state's business registry and the USPTO trademark database, and grab the matching domain and social handles. An LLC registers its name when it files. A sole proprietor operating under any name other than their own legal name usually needs a DBA ("doing business as") filing with the county or state. See what is a DBA.
Step 6: Get an EIN
An Employer Identification Number is a federal tax ID for your business. It is free and issued immediately when you apply online with the IRS. You need one if you have employees, operate as a multi-member LLC or corporation, or file certain tax returns; many sole proprietors get one anyway to keep their Social Security number off W-9 forms. Our guide on how to get an EIN walks through the form, and EIN vs SSN explains when each is used.
Step 7: Get licenses and permits
Almost every business needs something, even if it is only a general business license from the city or county. Regulated activities need more:
- Food: health department permits, food handler certificates, cottage food registration for home kitchens.
- Trades: state contractor, electrical or plumbing licenses.
- Childcare: state childcare licensing and background checks.
- Transport: USDOT number and operating authority for interstate trucking.
- Sales tax: a seller's permit if you sell taxable goods or services.
- Home-based: a home occupation permit and zoning approval in some cities.
Our step-by-step guide on how to get a business license shows where to look at city, county and state level.
Step 8: Open a business bank account
Keep business money separate from personal money from the first transaction. It makes bookkeeping and taxes far simpler, supports the liability protection of an LLC, and looks more professional when clients pay you. Banks usually ask for your EIN or SSN, formation documents or DBA certificate and ID. Compare monthly fees, transaction limits and payment features in our guide to business bank accounts.
Step 9: Set up bookkeeping, invoicing and payments
Decide now how you will quote, invoice, get paid and record every transaction. A simple setup:
- Choose accounting software or a spreadsheet and set up expense categories.
- Create an invoice layout with your business name, contact details, invoice number, dates, line items, tax and payment terms. Our free invoice generator does this in minutes.
- Pick a numbering system (for example 2026-001) using our invoice number generator.
- Set payment terms, such as due on receipt or net 15, and state them on every invoice. See invoice payment terms.
- Offer easy payment methods: bank transfer, card, or a card reader for in-person work.
- Record payments weekly and follow up on overdue invoices.
If you operate as an LLC or sole proprietor, our guides on how to invoice as an LLC and how to invoice as a sole proprietor show exactly what to include.
Step 10: Understand your taxes
- Income tax: sole proprietors and single-member LLCs report profit on Schedule C.
- Self-employment tax: 15.3% on net earnings for Social Security and Medicare (with the Social Security part capped each year). See self-employment tax.
- Estimated taxes: pay quarterly if you expect to owe $1,000 or more for the year. See quarterly estimated taxes and how much to set aside for taxes.
- Sales tax: register and collect where your goods or services are taxable. Check sales tax by state and use our sales tax calculator.
- Payroll tax: once you hire, see hiring your first employee.
Keep a calendar of deadlines and consider a one-off session with an accountant in your first year.
Step 11: Get insurance
Common policies for small businesses include general liability (injury or property damage to others), professional liability or errors and omissions (mistakes in advice or services), commercial auto (vehicles used for business), commercial property, and workers' compensation, which most states require once you have employees. Many clients, landlords and platforms require proof of insurance before they work with you, so get quotes from at least two brokers.
Step 12: Launch and find your first customers
- Create a Google Business Profile and a simple website with prices or a clear way to request a quote.
- Tell your network and ask for introductions.
- Ask every early customer for a review and referral.
- Choose one or two marketing channels and measure cost per customer.
- Send quotes fast and invoice the day the work is done.
Worked example: starting a lawn care business on $4,000
Alex starts a lawn care business in spring (see our full guide on how to start a lawn care business). Illustrative figures:
| Item | Cost |
|---|---|
| Single-member LLC filing | $150 |
| City business license | $75 |
| Used commercial mower, trimmer, blower | $2,400 |
| Liability insurance deposit | $300 |
| Flyers, yard signs and website | $350 |
| Fuel and supplies (first month) | $250 |
| Reserve | $475 |
| Total | $4,000 |
At $45 per weekly mow and 25 regular clients, Alex bills about $4,500 a month (25 x 45 x 4 weeks). He sends monthly invoices on the first of the month, due in 15 days, using a lawn care invoice template. Equipment is paid back within the first month of full bookings, and the reserve covers the slow first weeks.

Common mistakes when starting a small business
- Spending before validating. Buying equipment or inventory before anyone has agreed to pay.
- Underpricing. Prices must cover materials, overhead, taxes and a fair wage for you. Compare with average profit margins by industry.
- Mixing personal and business money. It complicates taxes and can weaken LLC protection.
- Skipping licenses or sales tax registration. Penalties and back taxes can exceed the cost of doing it right.
- No reserve. Sales almost always ramp up more slowly than planned.
- Slow or sloppy invoicing. Late invoices mean late cash. Invoice on completion with clear terms.
- Forgetting estimated taxes. A big April bill catches many first-year owners.

Frequently asked questions
How much money do I need to start a small business?
It depends on the business. A home-based service such as consulting, tutoring or bookkeeping can start for a few hundred to a few thousand dollars, while businesses that need premises, vehicles or inventory, such as a food truck or a trucking company, can need tens of thousands or more. Build an estimate from real quotes, add three to six months of fixed costs as a reserve, and add 10% to 20% for contingencies.
Do I need an LLC to start a small business?
No. In most US states you can start as a sole proprietor simply by doing business, and register a DBA if you use a name other than your own. An LLC adds liability protection, separates business and personal assets more clearly and can look more professional to clients. It also brings state filing fees and annual report obligations. Many owners start as sole proprietors and form an LLC once the business has real revenue or risk.
Can I start a business while working a full-time job?
Yes, and many people do to test demand before quitting. Check your employment contract for non-compete, moonlighting or intellectual property clauses, and avoid using your employer's time or equipment. Keep the side business's finances separate from day one, track income and expenses, and remember to pay estimated taxes on side income, because no employer is withholding tax from it.
What is the easiest small business to start?
Service businesses that use skills you already have and little equipment are usually easiest: cleaning, lawn care, dog walking, tutoring, bookkeeping, consulting, handyman work and freelance creative services. They need few permits, little inventory and can start from home. Easy to start does not mean easy to grow, so compare the earning potential and how much competition you face in your area.
Do I need an EIN if I am a sole proprietor?
Not always. A sole proprietor with no employees, no retirement plan and no excise tax obligations can generally use their Social Security number. However, many choose to get a free EIN from the IRS anyway, so they can give it to clients on Form W-9 instead of their SSN and open a business bank account more easily. LLCs with employees and multi-member LLCs need an EIN.
How long does it take to start a small business?
The paperwork can take as little as a day to a few weeks: an EIN is issued online immediately, and many states process LLC filings within days, although some take longer. Licenses and permits for regulated businesses, such as food, childcare, trucking or contracting, can take weeks or months. Planning, testing the idea and finding first customers usually take longer than the registration itself.
Do I have to file a beneficial ownership information (BOI) report?
Following FinCEN's interim final rule in March 2025, companies created in the United States and their US owners are exempt from BOI reporting under the Corporate Transparency Act. The requirement now applies only to certain foreign companies registered to do business in a US state. Rules in this area have changed several times, so check FinCEN's website for the current position when you form your company.
What taxes does a new small business pay?
Most new US small businesses deal with federal income tax on profit, self-employment tax for owners of sole proprietorships and LLCs, state income tax in most states, sales tax if they sell taxable goods or services, and payroll taxes once they hire employees. Owners usually pay income and self-employment tax through quarterly estimated payments. This is general information, so confirm your obligations with a tax professional.
How do I get my first customers?
Start with people who already know and trust you: past employers, colleagues, friends and local community groups. Set up a Google Business Profile, ask every early customer for a review and referral, and focus on one or two marketing channels your customers actually use. Make it easy to buy by sending clear quotes quickly and professional invoices with simple ways to pay.
What is the most common reason small businesses fail?
Running out of cash is the most common practical reason, often caused by weak demand, underpricing, high fixed costs or customers paying late. You can reduce the risk by testing demand before spending heavily, pricing to cover all costs and a fair salary, keeping fixed costs low, invoicing promptly with clear payment terms and building a cash reserve before you need it.
